    Has anyone used a PVC pipe for free flow?

    I was thinking about doing that but im a little nervious. It is like a 10 cent peice keeping a $10,000 ski floating but how different could it be from riva's old free flow. Has anyone done this before?

    Been ther Sunk that!! Don't do it!!!!! I sunk my 04"
    RXP by doing just that. The clamps will not hold tight enough to the PVC, and backpressure WILL blow it loose, and sink in seconds. Hope u have a BIG bilge pump. The pipe they sell has a lip on each end to keep the clamps from blowing loose.

    As it sunk down to the handle bars a boat threw me a line, and pulled it to shore, so I could drain it, and put it back together. No sealant at that time , but I wasn't about to TRY it again. Maybe if u sanded it real rough, and glued it , and double clamped it on both ends, it MIGHT hold

    Don't be cheap. Muffler shop for a piece of scrap and have them flare the ends. Cost me $5 at a Mieneke. I went directly to the work bay and bypassed the front desk penny pincher. I'm sure the mechanic put the cash in his pocket, took him like 3 minutes to flare the pipe ends.
